Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed March 8,1907. Serial No. 361,212.

ject oi the invention is to provide ilnproved rmeans for regulating the tension oi this spring.

The invention consists in the construction and combination of parts to be more l'ully described hereinaitei` and particularly set iorth in the claims.

Reference is to be had to the accompanying drawings lorming a part ol this specification, in which similar characters oi relerence indicate corresponding parts in all the figures.

Figure 1 is substantially a plan of the device, the upper portion th ereoi being shown in cross section, together with certain other parts near the middle oi the view; this view may be considered as a section on the line l1 of Fig. 2; Fig. 2 is substantially a longitudinal vertical section, certain parts being shown in elevation; Fig. 3 is a cross section, the upper portion o this view being shown in elevation; and Fig. 4 is a detail oi parts oi the governor'.

Referring more particularly to the parts, 1 represents a globe valve, the lower portion ol' which is iormed with a flange 2 adapted to be bolted to a pipe connection or directly to a steam chest. At the side a similar flange 3 is provided through which the steam enters the valve. Through the flange 3 there is an inlet opening 4, in the inner extremity oi which a valve seat 5 is provided or a throttle valve 6, said throttle valve being carried upon the extremity o a threaded stem 7. This stem is mounted in a guide or bonnet S which is screwed into the glove valve l opposite the inlet opening 4', and the interior of the glove valve is formed with a closed cl 1amber or inner globe 9 into which the steam is admitted when the hand-wheel 10 is rotated in the proper direction to open the throttle valve.

1n the wall oi the inner chamber or globe 9, on the upper' side, an opening 11 is provided, oi circular form, and above and around this opening the valve body 1 is [oi-med into afl-ange 12. Upon this flange 12 there is seated a disk 13, the middle central portion oi which is iormed into a downwardly projecting valve body 11i. The lower extremity oi this valve body 14: is received in the opening 11, whereby a tight fit oi the parts is formed. The interior oi the valve body 14 is iormed with a conical bore 15 in which there is received a hollow conical plug 16, the lower extremity whereof is open as shown, so as to admit steam into the interior ot the plug from theinner chamber 9. Th c space surrounding the valve body 14 is in communication with the outlet opening 17 from the flange 2 and the interior oi the globe body 1.

In the wall of the valve body 14 a plurality oi slots or ports 18 are formed, and similar ports 19 are iormed in the plug 16, which are adapted to register with the ports 1S. On the upper lace of the disk 13, an upwardly projecting stud 20, of relatively large diameter, is termed, and this stud passes through an opening iormed in the flange 21 oi a governor bracket 22. 1n this way the flange 21 seats upon the disk 13 in such a way that the parts may be connected together by through bolts o1' studs 23, las indicated in Fig. 1. The disk 13 is provided with a central opening through which a valve stem 2i passes upwardly; the lower extremity oi the said stem being rigidly attached in the head or upper end of the plug 16. This stem 24 projects above the upper surface of the stud 20 and the Hange 21, and has rigidly attached thereto a radially projecting arm 25. The plug 16 is held upon its seat by means ol a leaf spring 26 iorni ed with a hub 27 which presses against the under side oi the arm 25 at the stein, as shown. This spring 26 is formed with oppositely projecting legs which incline slightly in a downward direction, the extremities oi the legs resting upon the upper iace of the flange 21, as shown. 1t should be understood that the spring 26 in no way prevents the rotation of the stem 24.

We shall now describe the governor mechanism ior controlling tlie'governor valve li. On one side, the bracket 22 is 'formed into an elongated bearing 2S, as indicated most clearly in Fig. 2. and in axial alinement with this bearing, on the opposite side, the bracket is formed into a guide sleeve 29A vThis guide sleeve 29 and the bearing 2S are connected integrally by a yoke 30, as shown. Slidably mounted in the bearing 28 we provide a governor spindle 31. 1n the guide-sleeve 29 there is a thrust-head 34 formed into a shoulder 32 to receive the thrust oi the spring 33, the said spring being oi helical iorm and disposed about the reduced portion oi the head, as indicated. The outer suriace oi the sleeve 29 is threaded or the attachment oi an adjusting wheel 35, said wheel being formed near its outer end with a shoulder 36 against which the opposite end oi the spring 33 thrusts. Beyond this shoulder 36 a bore 37 is formed in the wheel, oi reduced diameter, and in this bore the extremity ot the thrust-head 34 is slidably mounted.

Within the bearing 2S a tubular sleeve 3S is provided, and the inner extremity ot this sleeve projects beyond the inner end oi the bearing, and is provided with a rigid collar 40 which holds the sleeve in position. The outer extremity of the sleeve projects beyond the outer end oi the bearing, and is threaded to receive a governor hub 4l. In this hub 4l arms 42 mounted between transverse webs are pivotally 43, and these arms ar'e provided with we'ghts or balls 44, which are adapted to ily out when the governor head dicated, these arms 42 pass tlnorrgh slots 45 formed in the lnrb 4l. The inner extremities of the arms 42 ar'e formed into toes 46 which project over and press against the end of the spindle 3l, as indicated in Fig. 2. Upon the hub4l a belt prrlley 47 is attached, which is adapted to receive a belt from a suitable part of the engine, so that the governor' will be rotated continuously when the engine is in operation.

The end of the spindle 3l at the pulley into a square head 3l disposed between the webs 43, as indicated in Fig. 4. From this arrangement, when the pulley is rotated the spindle 3l will also rotate. rlhe inner end of the thrust head 34 is formed with a. r'educed tip 34a and this tip extends into the bor'e in the hub of an ar'm 49, the arm being' rigidly attached thereto by a set screw 34D, as indicated. On the inner' end ot the spindle 3l. a reduced neck 4S is formed, which is loosely mounted in the opposite end of the bore of the hub, so that its end abuts against the end of the thrust head. In this way the hub of the ar'm forms a socket for thertail end of the governor spindle.

Near its outer end the ar'm Ai9 is provided with a pin 50 which extends through a slot 5l for'med 4in the end of the arm 25 aforesaid. From this arrangement it should be understood that when the pulley 47 is r'otated, the balls 44 will tend to ily outwardly by centrifugal force, and the toes 4G will operate to shift the spindle 3l toward the lelt, tending to compress the spring On account of the shifting movements of the arm 4.9, which will result as a consequence of the shifting or sliding movement of the spindle, the arm 25 will be rotated in such a way as to rotate the stem 24. .ln this way the plug lli is rotated so as to close, more or less, the amount of opening through the por'ts 1S and i9. In this way the valve i4 will act as a govis rotated. As inis formed er'nor' valve, the amount of opening through which will depend upon the speed of the engine.

We provide means for adjusting the amount of tension upon the spring. For this purpose, the thrusthead 34 is made of tubular form, the outer end being closed by a plug 52. Through this plug there is slidably mounted an indicator' stem 53, the outer end whereof is rotatably mounted at 54 in an opening formed in the end of the wheel 35. Just within the plug 52 tlrisindicator stem 5S is offset laterally and passes through an opening 5" in the forward end of the sleeve. Beyond this point rt is offset laterally and downwardly so as to form a shank 5G which passes into the iuter'ior of an indicator 57, said indicator being mounted on the ripper' face of the flange 2l, as shown. Within the indicator, the shank 56 is pivotally attached to a segment 58, which segment, through the medium of a gear train 59, operates to rotate a needle 60. The

i l l l l l il t i t g l l i i indicator 57 is provided with a dial 6l with which the needle coperates. The arrangement is such that when the hand-wheel 35 is unscrewed sutl'iciently to relieve the spring 33 of airy strain, the needle (30 will then register' zero on the dial. As the hand-wheel is screwed up, however, the needle will indicate at all times the amount of compression tao-which the (spring is subjected. It should be understood that in practice, the compression to which the spring will be subjected will depend upon the number of revolutions at which the engine is to run. At slowAspeeds, of course, the tension on the spring will be smaller' than at high speeds,

It will be observed that the disk 13 constitutes a cover for the valve body.

Having thus described our invention, we claim as new and desire to secure by Letters Pa tent:
